Transcription of I-96 Flex Route Project Board Rebuilding Michigan
1 Rebuilding MI Corridors I-96 flex Route Project I-275/I-696/M-5 Interchange to Kent Lake road MDOT Job Number 124103. Rebuilding MI Corridors I-96 flex Route is a Rebuilding MI Corridor Rebuilding MI Corridors are part of the Rebuilding MI bond program focused on state highways and bridges that are critical to our economy and carry the most traffic. Rebuilding MI Corridors will be designed and constructed as a single Project . MDOT will environmentally review these corridors as single projects to identify any potential cumulative impacts.

Proposed Ramp Metering What will ramp metering look like? Ramp metering uses traffic signals on ramps to Expected benefits of flex lane and smooth the flow traffic onto the freeway to: ramp metering: Reduce congestion by managing the number of 1. Improved Safety entering vehicles. Reduced rear-end crashes Break up platoons that form on the ramp and Reduced merge crashes 2.
3 Improved Travel Time Reliability have difficulty entering the freeway. Improved travel time consistency How it works: Eastbound morning up 1. Ramp Metered When Flashing signs alert to 65%. motorists that the signal is on. Westbound afternoon 2. Enter traffic forms two lanes and is prepared to up to 75%. stop at signal. Reduced peak period duration 3. On red signal, traffic stops at white stop bar as it Eastbound morning up would for any other traffic signal. to 80%. 4. Alternating green signals allow the next Westbound afternoon motorist closest to the signal to enter freeway.
4 Up to 67%. States using ramp metering: Arizona Kansas Oregon California Minnesota Pennsylvania Colorado Missouri Texas Florida Nevada Utah Georgia New York Washington Illinois Ohio Wisconsin Washington also uses ramp meters Use of Ramp Metering in Minnesota 4. Proposed Gantry Layout 1. flex Lane OPEN. or CLOSED. 5. Proposed Gantry Layout 2. flex Lane OPEN. with ADVISORY. SPEED. 6. Expected Project Benefits Reduced travel times Notification of slow downs ahead Reduced stop-and-go Improved travel time reliability 7. Project Background and Need 12 miles from Kent Lake road to I-275/I-696/M-5.
5 Main corridor between Lansing and Detroit 163,000 vehicles per day Recurring directional congestion Eastbound in the morning Westbound in the afternoon Limited alternate routes Excessive travel times Inconsistent travel time reliability Frequent crashes Available existing wide median shoulders 8. Environmental Impacts Analysis will review impacts to: Natural Environment Community Impacts Air Public Engagement Wetlands Noise Water Quality Indirect/Cumulative Flora/Fauna Public Parks Detours Hospital Access Mall Access Special Event Access 9.
6 Proposed Project Work Installation of an Active Traffic Management System ( flex Lane) from Kent Lake road to I-275/I-696/M-5. interchange, including: ITS equipment to allow part-time peak-period median shoulder use, provide traffic warnings and advisory speeds and assist in incident management Ramp metering at 8 entrance ramps to help reduce congestion and improve travel time reliability and safety by breaking up entering traffic platoons 7 crash investigation sites along the outside shoulder to assist in clearing incidents 10.
7 Proposed Project Work (Continued). Full reconstruction of all lanes and shoulders of I-96 from Kent Lake road to approximately 1800'. east of Haggerty in the I-275/I-696/M-5. interchange reconstruction of the ramps at the Milford road and Novi road interchanges Pavement patching of the ramps at Wixom road and Beck road interchanges rehabilitation of the Beck road Park & Ride lot rehabilitation of 11 bridges and culvert work 11. Next Steps Construction Begin in the Fall of 2021/Spring of 2022. Complete in 2024. Construction Impacts Lane closures entire duration of Project Ramp closures during some construction stages 12.
